Vancouver Fraser Port Authority Hemmera Maplewood Marine Restoration Project CEMP - 1 - July 2018
1.0 INTRODUCTION
The Maplewood Marine Restoration Project (MMRP, or “Project”) is a habitat enhancement project
proposed by the Vancouver Fraser Port Authority (VFPA) Habitat Enhancement Program (HEP). HEP is a
VFPA program whose goal is to balance a healthy environment with infrastructure development
opportunities. HEP creates and enhances fish and wildlife habitat for habitat banking purposes, use as
offsetting for port infrastructure projects, or a combination of both. MMRP is a proposed HEP project
anticipated to enhance approximately seven hectares of low-value marine habitat into higher-value
marine habitat for fish, birds, and other wildlife. Proposed habitat enhancements include creation of a tidal
channel, subtidal rock reef habitat, eelgrass habitat, and intertidal flat habitat.
The following Construction Environmental Management Plan (CEMP) was developed with reference to
VFPA’s Project and Environmental Review Guidelines – Construction Environmental Management Plan
(PMV 2015). This CEMP, prepared by Qualified Environmental Professionals (QEPs), describes how the
Project will be managed during construction to avoid adverse impacts to the environment. This CEMP is
based on the design and Project details outlined in the 60% Design Report (AECOM 2018).
Once the Project is awarded, the selected Contractor will be responsible for developing a Project-specific
Environmental Protection Plan (EPP) to avoid potential adverse environmental impacts based on specific
equipment and refined construction methodologies. The Contractor’s EPP will be reviewed by VFPA’s HEP and will be provided to VFPA’s Project and Environmental Review (PER) team to confirm that it
conforms to the requirements of this CEMP and any conditions of regulatory approvals/permits.
Throughout construction, the Contractor will ensure that all Project construction activities adhere to this
CEMP and the Contractor’s EPP, in addition to applicable regulatory requirements.
2.0 PROJECT INFORMATION
2.1 LOCATION
The Project lies within VFPA jurisdiction on the north shore of Burrard Inlet, approximately two kilometres
east of the Ironworkers Memorial Bridge. The Project is immediately south of a wildlife conservation area
(the Maplewood Flats Conservation Area), which is leased to Environment and Climate Change Canada
and is managed by the Wild Bird Trust of British ColumbiaFigure 1.
The Project site covers approximately seven hectares and consists of two distinct areas: The Northeast
Basin, centered at approximately 49°18’10” N and 123°00’05” W; and, the Southwest Channel area
(located in the Southern Intertidal Area), centered at approximately 49°17’55” N and 123°00’25” W
(Figure 1).

Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 3 - July 2018
2.2 PROJECT DESCRIPTION
Habitat in the Northeast Basin will be created by beneficially using approximately 87,000 m3 of dredge
material from the Southern Intertidal Area (resulting from the creation of the proposed Southwest
Channel), and approximately 95,000 m3 of imported clean fill material, to raise the elevation of the
existing substrate. Fraser River sand, or a suitable clean alternate (e.g., approved Sechelt sand), is
proposed as the additional fill material. This imported material is anticipated to be placed over the
dredge material from the Southwest Channel to form the upper sediment layer in the Northeast Basin.
The newly created intertidal flat habitat and shallow subtidal eelgrass habitat in the Northeast Basin will
be located between approximately +2.0 m and -2.0 m chart datum (CD). Construction of a rock dyke is
required to contain the fill material needed to establish the intertidal and shallow subtidal areas in the
Northeast Basin. Subtidal rock reef habitat south of the rock dyke, at the southernmost end of the
Northeast Basin, will be constructed by placing appropriately sized rock material between approximately
-3.0 m and -4.0 m CD. The rock reef habitat will be constructed using rock of varying diameter, with an
average (median) diameter (D50) of approximately 600 mm. A total of approximately 8,500 m3 of rock
material is anticipated to be placed in the Northeast Basin.
Rock reef habitat will also be created in the Southern Intertidal Area following dredging of the Southwest
Channel. The Southwest Channel will improve tidal flushing in the Maplewood Basin and enhance
nutrient transport, improve water quality, reduce siltation of marine vegetation, and facilitate suspension
and distribution of eggs and larvae of pelagic spawning fish and invertebrates, including marine
vegetation spores. A total of approximately 14,000 m3 of rock material will be placed in the Southwest
Channel, both along the base of the channel to function as subtidal rock reef habitat, and along the side
slopes of the excavated Southwest Channel to protect against scour from tidal currents as well as to
function as rock reef habitat. The rocks along the side slopes will have a D50 of approximately 500 mm,
and the rocks on the base of the channel will have a D50 of approximately 600 mm. The rock in the
Southwest Channel will be placed between approximately +2.0 m and -4.0 m CD.
Barge-mounted construction equipment will be required to cross over the shallow Southern Intertidal
Area during a high tide before the start of dredging. It is anticipated that the Southwest Channel will be
dredged using a barge-mounted clam-shell dredge. To facilitate placement of material from the
Southwest Channel into the Northeast Basin, it is anticipated that dredging will start from the inner (i.e.,
northeastern) end of the channel to avoid transporting and potentially grounding loaded, or partially-
loaded, scows on the shallow Southern Intertidal Area. Once the Southwest Channel is dredged to
design grade (i.e., -4.0 m CD), it is anticipated that loaded material scows will be able to enter/exit the
Project site during low tides (utilizing the Southwest Channel). Construction methodology details will be
refined as the Project advances to a procurement-ready stage.
Following construction, stabilization, and a final survey of the eelgrass bed location, native common
eelgrass (Zostera marina) will be transplanted from suitable donor beds into the Northeast Basin.
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 4 - July 2018
2.3 PROJECT SCHEDULE
Detailed design, permitting, and consultation and engagement will be undertaken throughout 2018 and
2019. Construction is anticipated to commence in mid- to late-2019. A preliminary proposed construction
schedule (AECOM 2018) is provided in Table 1. A detailed schedule will be determined following
procurement and Contractor selection.

2.3.1 Timing Windows
The annual marine/estuarine timing window of least-risk for Burrard Inlet is August 16th to February 28th.
This refers to the time period of reduced risk for important commercial, recreational or Aboriginal (CRA)
fish species. The majority of the construction work is scheduled to occur during this least-risk timing
window to mitigate risk of negative effects to juvenile salmonids. However, due to the potential material
settlement time required for sediment placement in the Northeast Basin, material placement may extend
beyond the end of the least-risk timing window (e.g., post-February 28th). Any work outside the window
would occur with appropriate mitigation in place.
The federal Migratory Birds Convention Act, 1994 (MBCA) exists to protect and conserve migratory
birds—as populations and individual birds—and their nests. Under the MBCA, no person shall, without
lawful excuse, be in possession of a migratory bird or nest, or, buy, sell, exchange or give a migratory bird
or nest or make it the subject of a commercial transaction. This Act restricts the deposit of harmful
substances in waters or areas frequented by migratory birds. As there is minimal anticipated overlap
between birds covered under the MBCA and Project construction activities, either spatially (i.e., no
construction activities proposed in the upland) or temporally (i.e., the majority of construction is proposed
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 5 - July 2018
outside the general nesting period of migratory birds1 in the region: mid-March to mid-August),
contravention of the MBCA is not anticipated.
However, the Project site is located adjacent to upland areas where there is potential to indirectly affect
birds and their active nests (e.g., due to noise). Should construction activities overlap with the general
nesting period of migratory birds in the region, extra precaution will be exercised to avoid causing harm to
birds and/or their active nests and eggs.
2.4 SITE DESCRIPTION
The Project site was historically an intertidal flat. Throughout the 1900s it was altered by activities
associated with dredging, gravel extraction, logging operations, and industrial use, resulting in the
development of the relatively deep Maplewood Basin (comprising the Northeast Basin and larger Main
Basin), and an intertidal area to the south of the Maplewood Basin, where the Southwest Channel is
proposed. Due to the depth, the lower portions of Northeast Basin (approximately -9.0 m CD) and Main
Basin are subject to poor flushing. Biological surveys have shown that, generally, the Project site has
relatively low habitat value with low diversity and abundance of marine life (Balanced 2017). The basins
are dominated by fine sediments. There is also some wood debris accumulation present in the Northeast
Basin from historic log handling operations.
A biophysical survey of the Project site was conducted in the fall of 2017 and consisted of both
underwater dive surveys and land-based assessments. Additional information on the assessments and
existing biological conditions is available in the Biophysical Survey (Balanced 2017) and the Ecological
Conditions Report (Hemmera 2018a). Archaeological assessments of the Project site (including an
Archaeological Overview Assessment and a Preliminary Field Reconnaissance) were undertaken in early
2018 (ILP 2018).
1 The general nesting period for migratory birds in Canada (Government of Canada 2017) covers most federally protected
migratory bird species; raptor nesting windows are more varied, and are described in Guidelines for Raptor Conservation During Urban and Rural Land Development in British Columbia (MOE 2013).

3.2 ENVIRONMENTAL MONITOR RESPONSIBILITIES
To ensure adherence to the environmental protection objectives and conditions of Project permits and the
requirements of this CEMP and the Contractor’s EPP, the Contractor will be required to retain a QEP in
the role of the Project’s Environmental Monitor (EM), who will work on behalf of the Contractor. The EM
will need to be approved by VFPA’s HEP prior to Project commencement to ensure they meet the
qualifications as outlined in the Project procurement documents. The EM will be responsible for ensuring
that mitigation measures are properly implemented by the Contractor and are functioning as intended.
The EM may indicate that the mitigation measures be adapted if the need arises. Typical responsibilities
of the EM include those identified below; however, specific items may be updated based on refinements
to the construction methodology following selection of the Contractor and throughout construction.
• The EM will review the Contractor’s work procedures to ensure functionality and compliance with
this CEMP, the Contractor’s EPP and applicable regulations, standards and best management
practices (BMPs).
• The EM will communicate the requirements of Project permits, this CEMP and the Contractor’s EPP to the Project construction team members during pre-job and tailgate meetings.
• An appropriate schedule for environmental monitoring will be established between the EM,
Project Manager and regulatory agencies. The EM will be on-site as per the schedule established
between parties prior to Project start. However, the monitoring frequency may be adapted
depending on specific site conditions and work progress.
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 7 - July 2018
o Monitoring events will be undertaken throughout construction at an appropriate frequency
based on the specific work tasks (e.g., dredging and fill placement), and potential for
adverse effects to occur.
o Monitoring will be conducted with greater frequency during periods of inclement weather
(e.g., heavy precipitation, and rough oceanic conditions).
o Full-time monitoring will be undertaken during start-up of any new phases of the Project
and during installation of environmental protection measures (e.g., installation of a silt
curtain).
• The EM will remain on-call during non-critical work periods to respond to emerging environmental
issues.
• The EM will support and liaise directly with the Contractor to provide technical advice for the
purpose of resolving situations that may affect the environment. The EM will advise the
Contractor if construction activities have caused, or are likely to cause, an environmental incident
and make recommendations for corrective action.
• The EM will have the authority to modify and/or halt any construction activity at any time if
deemed necessary for the protection of the environment.
• The EM will maintain complete records of activities related to the implementation of the CEMP
and Contractor’s EPP. This will include any measurements taken (e.g., pH, turbidity, temperature,
conductivity, etc.), photographs, analyses, and incident reports. The EM will document any
potential adverse effects to the environment and will include the nature of the effect, its cause,
mitigation and/or remediation measures implemented, and whether a work stoppage was
ordered. This will be used by the EM to complete and submit environmental monitoring reports to
the Contractor, which will subsequently be submitted to VFPA’s HEP.
3.3 HEP ENVIRONMENTAL MONITOR RESPONSIBILITIES (INDEPENDENT MONITOR)
VFPA’s HEP will also retain a QEP in the role of the Project Independent Monitor (IM) to provide auditing
level environmental services for the Project. The IM will be responsible for:
• Reviewing the Contractor’s EM reports.
• Conducting periodic spot checks of the Project site to verify compliance with this CEMP, the
Contractor’s EPP and applicable regulations, standards and BMPs. If deemed necessary for the
protection of the environment, the IM will have the authority to issue stop work orders.
• Submitting reports to VFPA’s HEP.
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 8 - July 2018
3.4 APPLICANT/CONTRACTOR RESPONSIBILITIES
The Contractor will be responsible for ensuring that the Project is undertaken in accordance with the
conditions of the permits/approvals, this CEMP and the Contractor’s EPP as well as any applicable
federal, provincial and municipal regulations. The environmental responsibilities of the Contractor are
identified below; however, specific items may be updated based on refinements to the construction
methodology following selection of the Contractor and throughout construction.
• The Contractor will review conditions of the CEMP and their EPP with their field staff and sub-
contractors prior to commencing work. The Contractor will be responsible for ensuring that their
field staff and sub-contractors understand the BMPs for this Project and know how to properly
install protection measures.
• The Contractor will comply with written or verbal instructions from the EM with respect to
conducting activities in compliance with the mitigation measures outlined in this CEMP and
Contractor’s EPP, and per applicable regulations, standards and permits.
• The Contractor will correct deficiencies and any non-compliance issues upon direction from the
EM whether written or verbal. Corrections should be made as soon as reasonably possible,
ideally within 24 hours.
3.5 RELEVANT ENVIRONMENTAL PERMITS
Environmental permits, documents and/or exemptions that are anticipated to apply to the Project are
highlighted in Table 3. Note that obtaining other construction-related permits (e.g., scientific fish
collection permits) will be the responsibility of the Contractor conducting the works and these have not
been accounted for in Table 3.

4.0 MITIGATION MEASURES AND ENVIRONMENTAL SPECIFICATIONS
The following section outlines environmental standards, guidelines and BMPs applicable to the Project.
Additional mitigation measures may also be outlined in the VFPA PER permit or may be provided by
other regulatory agencies. These will be incorporated into the Contractor’s EPP developed for the Project.
4.1 GENERAL PRACTICES - MARINE WORKS
Marine construction-related activities may take place from marine-based barges, derricks and scows.
Potential negative effects to aquatic resources during construction-related activities will be mitigated by
implementing appropriate measures as outlined below.
• The majority of the construction work is scheduled to occur during the Burrard Inlet least-risk
timing window (i.e., August 16th to February 28th). Any work outside the window would occur with
appropriate mitigation in place.
• During severe weather conditions (e.g., >70 km/h winds), work may be suspended if the
effectiveness of mitigation measures is reduced (e.g., silt curtain application during dredging
activity).
• Barges and other vessels will not ground on the foreshore or seabed, or otherwise disturb the
foreshore or seabed (including disturbance as a result of vessel propeller wash), excepting only
such disturbance as is reasonably required resulting from the use of barge spuds and anchors.
4.2 SITE ACCESS, MOBILIZATION AND LAYDOWN AREAS
Prior to construction, the method by which the Contractor plans to access the Project site and mobilize
construction-related equipment will be clearly described. Any challenges for site access or mobilization
will be identified. It is currently anticipated that construction equipment will need to mobilize to access the
Maplewood Basin during high tidal conditions at commencement of construction. However, additional
information including a drawing/figure showing access points and anchoring areas at the Project site, is
anticipated to be incorporated into the Contractor’s EPP. Mobilization will be planned to minimize the
number of trips to and from the Project site.
4.3 SEDIMENT CONTROL AND MANAGEMENT
The Contractor will not permit sediment, sediment-laden waters, or other deleterious substances to enter
the water during the Project. As described below, the Contractor will carry out all physical activities in a
manner that prevents induced sedimentation and induced turbidity of local waters, and the release of
sediment, sediment-laden waters, and turbid waters to the aquatic environment.
• Appropriate dredging equipment will be selected and operated in a manner that reduces spillage.
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 10 - July 2018
• The direct or indirect release or deposit of sediment or sediment-laden water into the aquatic
environment outside the active work area (e.g., outside any silt curtains used for the Project), will
be minimized during the works. In this regard, reference will be made to the water quality criteria
described in the British Columbia Water Quality Guidelines (MOE 2018).
• Rock and fill materials (i.e., sand/silt) used for the Project will be demonstrated to be clean and
free of environmental contamination.2
• The placement of rock and fill material will occur in a controlled manner to limit generation of
suspended sediment and increased turbidity.
• While it is anticipated that dredged and placed sand will settle out of suspension relatively quickly
due to the high settling velocity of sand and the relatively low velocity of waters at the Project site
(AECOM 2018), it is anticipated that silt curtains will be used (e.g., Type III silt curtains that are
designed to withstand current velocities of up to 1.5 m/s (AECOM 2018)). Silt curtains will be
used, where technically feasible, to limit the release of turbid waters during dredging of the
Southwest Channel and placement of fill in the Northeast Basin.
4.4 MACHINERY AND EQUIPMENT
For machinery and equipment working on the Project site, the Contractor will ensure that:
• All machines and equipment are in good operating condition and meet applicable requirements
for serviceability and exhaust emissions. Equipment will be free of leaks, excess oil and grease.
• Equipment is cleaned off, and visually inspected for, invasive species and noxious weeds prior to
arriving on, and leaving, the Project site.
• Daily inspections are undertaken for all equipment used on the job.
• Equipment used around water is equipped with biodegradable hydraulic fluid, as is practical.
• Equipment maintenance occurs off-site, where and when possible. If equipment maintenance is
required on-site, activities will be undertaken overtop an impermeable layer.
• No equipment is washed within the Project area or near open water.
• Equipment is operated at optimum rated loads and is turned off when not in use to minimize
exhaust and noise emissions. Equipment producing excessive exhaust or noise will be repaired
or replaced.
• Refueling of equipment occurs in a contained area as far away from the water as possible.
Funnels and drip trays will be used to control on-ground spillage of fuel. The refueling area will
have a spill containment kit immediately accessible and personnel will be knowledgeable in the
use of the kit. 2 Physical and chemical characterization of the potential Source Sites (Southwest Channel and Fraser River sands)
and the Receiving Site (Northeast Basin) sediments was completed by Hemmera in 2018. The analyses indicated that sediment from the Source Sites is of better quality than the Receiving Site, and placement of material from the Source Sites is not likely to degrade the receiving environment since the concentrations of potential contaminants of concern appear to be less than the Receiving Site sediments (Hemmera 2018b).
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 11 - July 2018
4.5 AIR QUALITY
The Project will be undertaken from water by barge. Upland activities (e.g., excavation with potential to
result in dust generation and/or track out of vehicles) are not anticipated. However, air emissions such as
equipment exhaust and vapours associated with marine construction-related activities will be minimized
and managed to avoid adverse health, safety, nuisance and other environmental effects on- and off-site.
The following standard BMPs for air quality will be applied for machinery working on the Project site:
• All equipment, vehicles and stationary emission sources will be well-maintained and used at
optimal loads to minimize emissions.
• Vehicles or equipment producing excessive exhaust will be repaired or replaced prior to being
used on the Project.
• Once a diesel engine/generator has reached its operating temperature, the engine will not be left
idling when no work is required.
• Stationary emission sources (e.g., portable diesel generators, compressors, etc.) will be used
only as necessary and turned off when not in use.
• Equipment and vehicles will be turned off when not in active use.
4.6 NOISE
Work is anticipated to occur outside VFPA’s standard regular working hours (i.e., Monday to Saturday
between 7:00 am and 8:00 pm, excluding holidays). The affected surrounding community will be notified
(as appropriate) of the nature and duration of noisy operations in advance of work taking place and/or
when work is required outside regular working hours.
Noise generation and vibrations resulting from equipment and associated activities during construction
will be addressed through appropriate noise management practices. The following BMPs will be
implemented to minimize noise generation:
• All equipment will be properly maintained to limit noise emissions and fitted with functioning
exhaust and muffler systems. Machine covers and equipment panels will be well-fitted and will
remain in place to muffle noise. Bolts and fasteners will be tight to avoid rattling.
• Engines will be turned off when not in use.
4.7 AQUATIC SPECIES AND HABITAT
Aquatic species such as fish, marine mammals and marine invertebrates have potential to be
encountered and/or affected by Project works.
• To minimize the risk of direct or indirect effects on fisheries species, the heavy construction work
(dredging activities and placement of materials) will take place during the applicable annual least-
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 12 - July 2018
risk timing window (i.e., August 16th to February 28th), where possible. However, due to the
potential material settlement time required for sediment placement in the Northeast Basin,
material placement may extend beyond the end of the least-risk timing window (e.g., post-
February 28th). Any work outside the window would occur with appropriate mitigation in place.
• In the Northeast Basin, a pre-construction dive survey will be conducted in advance of fill
placement to inform the appropriate level of mitigation and salvage effort required (e.g., to assess
the density of crabs in the fill area). An aquatic life salvage (e.g., for crabs with the use of
perimeter crab traps) may subsequently be conducted in the Northeast Basin prior to the
placement of rock and fill materials. Salvaged organisms will be relocated to similar habitat
outside the Northeast Basin.
• In advance of dredging of the Southwest Channel a salvage of marine organisms will be
undertaken either during a low tide and/or during high tide via divers. Salvaged marine organisms
will be relocated to nearby appropriate habitats not affected by construction.
• Species to be targeted with salvage efforts in the Northeast Basin and Southwest Channel will be
CRA invertebrate species that may be present within the Project area including, but not
necessarily limited to, Dungeness crab (Metacarcinus magister), red rock crab (Cancer
productus), California sea cucumber (Parastichopus californicus) and urchins (Strongylocentrotus
spp.). Fin fish will not be targeted by the salvage as they are likely to move out of the work area
as construction activities begin.
• Sensitive marine habitats (e.g., existing nearby kelp and eelgrass communities) will be
appropriately marked (e.g., with buoys), georeferenced, and avoided during in-water works.
• Slow commencement of in-water construction activities is recommended to encourage mobile
aquatic species to leave the construction area.
• Mitigation measures as outlined in the sections above (e.g., in relation to noise, sediment control
and machinery/equipment) will be implemented to minimize negative effects to aquatic species
and their habitat.
• Marine mammal safety zones will be established around the Project site, including a 1,000 m
safety zone for cetaceans (whales, dolphins, and porpoises) and a 150 m safety zone for
pinnipeds (seals and sea lions). If a marine mammal enters its respective safety zone during in-
water construction activities, a work stoppage will be implemented if the marine mammal is at risk
of physical harm or is observed to be disturbed by construction activities. Construction activities
may only resume once the marine mammal has been confirmed to have left the safety zone or
has not been sighted for 30 minutes. While it is not anticipated that construction activities will
result in noise levels that exceed the acoustics thresholds of fish and marine mammals (i.e., no
pile driving is proposed as part of the Project), if activities are anticipated to result in the
generation of loud underwater noises, a marine mammal observer will be required to monitor the
noisy work and implement an underwater noise monitoring program.
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 13 - July 2018
• Dependent on the specific construction methodology proposed, additional mitigation measures
will be incorporated into the Contractor’s EPP, as appropriate.
4.8 TERRESTRIAL VEGETATION AND WILDLIFE MANAGEMENT
Terrestrial vegetation is not anticipated to be affected as a result of the Project. In general, Project-related
effects to local terrestrial wildlife surrounding the Project areas are anticipated to be minimal and are
primarily limited to possible interactions with bird species that may use the Project area for foraging
and/or the surrounding area for nesting purposes. As such, negative construction-related effects to
terrestrial species will generally be limited to noise disturbance (see Section 4.6). To avoid attracting
wildlife to the Project site, an effective garbage management system will be implemented during
construction.
The majority of work is anticipated to occur during the fisheries least-risk timing window, outside of the
general nesting bird window. However, should construction activities extend into the general nesting
period of migratory birds in the region, extra precaution will be exercised to avoid causing harm to birds
and/or their active nests and eggs.
A known osprey nest (protected under the BC Wildlife Act (s.34b)) is located on a piling approximately
130 m southeast of the Northeast Basin. Due to the sensitivity of the Project being located adjacent to a
conservation area, it is recommended that a 100 m buffer plus 1.5 tree lengths (conservatively considered
20 m for this osprey nest on a marine pile) be implemented during Project construction as a best
management practice. Land contouring, dredging, construction, or any other unusual or sudden loud
activity will not be conducted within this 120 m buffer during the osprey breeding window (i.e., March 21
to September 5). This is in accordance with Guidelines for Raptor Conservation during Urban and Rural
Land Development in British Columbia (MOE 2013).
4.9 ARCHAEOLOGICAL RESOURCES
A recorded archaeological site (a fishweir) is situated in the existing intertidal flats immediately southeast
of the Northeast Basin. To mitigate potential effects to this archaeological resource during habitat
enhancement initiatives in the Northeast Basin, a 25 m buffer (archaeological site work avoidance zone)
will be implemented around the archaeological site. Crews will be briefed on the location of this work
avoidance zone (ILP 2018).
If the Contractor encounters, or expects to encounter an actual or potential archaeological resource
during construction activities, they will implement a Chance Find Procedure in alignment with the
following:
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 14 - July 2018
• Immediately stop any activities that might disturb the archaeological resource or the site in which
it is contained.
• Not move or otherwise disturb the artifacts or other remains present at the site.
• Mark the location of the site to prevent additional disturbances.
• Immediately notify VFPA by email and phone.
4.10 NAVIGATION
To avoid conflict with other vessels and water users, the following BMPs will be implemented:
• Prior to the commencement of any vessel-related activities, the appropriate Canadian Coast
Guard and Marine Communication and Traffic Services centre will be notified regarding the
issuance of a Notice to Shipping to advise the marine community of potential hazards associated
with the Project.
• At least two days prior to commencing any construction or physical activities, the Harbour Master
and VFPA Environmental Programs will be notified.
• All vessels and equipment will be positioned in a manner that does not obstruct the line of sight to
navigational aids or markers.
• All vessels will exhibit appropriate lights and day shapes at all times.
• The Contractor will monitor the Very High Frequency (VHF) channel used for Marine
Communications and Traffic Services in the respective area at all times and participate as
necessary.
• The Contractor will be familiar with vessel movements in areas affected by the Project.
• The Project activities will not impede navigation or interfere with vessel operations.
• During night hours, equipment will be moored outside the navigation channel and lit in
accordance with all applicable regulations.
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 15 - July 2018
5.0 FUEL MANAGEMENT PLAN
The Contractor’s EPP will identify areas for equipment re-fueling and show this on a site plan. The fuel
management plan will provide a bulleted list of measures being incorporated during construction to
ensure the receiving environment is adequately protected from construction-related fuels and products on
the Project site. The following BMPs will be used for fuel management:
• Adequate spill containment materials will be within refueling areas at all time.
• Bulk fuel will not be stored within the Project area to prevent the possibility of leaks or
contamination.
• Where feasible, pre-fueling of equipment will occur prior to arrival within the Project area to
reduce the potential for spills and leaks.
• For refueling of skiffs and other mobile equipment, the following refueling procedures will be
implemented:
o Make sure the vessel is secure.
o Measure the quantity that is required, to be able to anticipate when the tank is nearly full.
o Never leave the area unattended while refueling.
• Where possible, one area will be designated for fuel transfer (e.g., a flat area that minimizes
potential for fuel spills to enter the marine environment).
• Fuel, oil, chemicals and other hazardous materials will be placed in a lockable enclosure of
sufficient volume to contain a spill.
• Refueling equipment and tanks will be clean and in good working order. Fuel tanks should be
situated within appropriate secondary containment (an impermeable containment facility capable
of holding 110% of the storage tank contents). This may be achieved through the use of double-
walled storage tanks or sit-in containers constructed out of impermeable material, such as
aluminum or plastic.
• If transferring fuel from a mobile tank to large machines, sorbent material will be placed around
the fuel inlet prior to dispensing. Pumping equipment with an approved hose and top-fill nozzle
will be used and a proper connection between the fuel source and machine will be verified. The
fill valve will be open while transferring fuel.
• Receiving tanks will not be overfilled.
• Smaller equipment will be placed in portable secondary containment and refuelled using
approved jerry cans.
• Any transportation of dangerous goods (i.e., fuel and lubricating oils) for construction equipment,
will be carried out in conformity with the federal Transportation of Dangerous Goods Act.
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 16 - July 2018
6.0 WASTE MANAGEMENT
Minimal construction waste is anticipated to be generated based on the nature of the Project. However,
the Contractor will maximize opportunities to reduce, reuse and recycle waste materials generated on the
Project site. All debris and waste material will be collected in the immediate working area within the
Project site. Waste material will be disposed at suitable upland locations. Contractors will adhere to all
applicable legislation with respect to the handling, transportation, and/or disposal of all materials related
to this Project (waste or otherwise). These regulations may include (but not be limited to) the BC
Hazardous Waste Regulations, Spill Reporting Regulations, Workers Compensation Board Regulations,
Transportation of Dangerous Goods Regulations, etc. The following BMPs will be implemented with
respect to waste management:
• Clean up of barges will be an ongoing maintenance activity.
• Any debris that is inadvertently lost overboard and deposited (floating or sinking) within the
marine environment will be recovered as soon as possible.
• Hazardous wastes generated could include waste petroleum products (e.g., engine oils and
lubricants) from machinery and equipment, spent batteries, solvents and cleaning agents, etc.
Contractors will provide labelled separate containers for potentially hazardous waste such as oily
rags and hydrocarbon absorbent pads.
• All hydrocarbon products and other hazardous wastes potentially present during construction will
be identified. The associated Workplace Hazardous Materials Information System and Materials
Safety Data Sheets of these products will be made available to all construction team members.
• All recyclable or compostable materials will be collected separately from general waste as per
Metro Vancouver Regional District requirements.
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 17 - July 2018
7.0 EMERGENCY RESPONSE
An integral part of effective environmental management during construction-related activities is a
comprehensive emergency response plan, which when initiated, allows for the rapid response of
emergency services and/or the containment and cleanup of environmental emergencies. The following
section provides a general outline for an effective response plan. The Contractor will be responsible for
ensuring a specific response plan is incorporated into their EPP.
7.1 EMERGENCY COMMUNICATION
The Contractor’s EPP will include a communication plan, including contact information for all parties who
are responsible for the Project, or are critical to the response or reporting of accidents or environmental
emergencies such as spills of oil, fuel or chemicals to a receiving waterbody. VFPA, Environment and
Climate Change Canada, Fisheries and Oceans Canada and the Provincial Emergency Management BC
Program (formerly the Provincial Emergency Program) are to be notified of reportable incidents. Below is
an example contact table (Table 4).

Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 18 - July 2018
7.2 SPILL RESPONSE PLAN
Prior to commencement, the Contractor’s EPP will establish an appropriate spill prevention, containment
and clean-up plan for hydrocarbon products (including fuel, oil, and hydraulic fluid) and any other
deleterious substances using standards, practices, methods and procedures to a good commercial
standard. The Contractor will ensure that appropriate spill containment and clean-up supplies are
available at the Project site at all times, and that all personnel working on the Project are familiar with the
spill prevention, containment and clean-up plan.
The EPP developed by the Contractor will include measures to be implemented as part of the spill
response plan such as:
• Identification of any/all hazardous materials/products as well as waste storage and secondary
containment. Materials Safety Data Sheets will be kept at the Project site and made available to
all construction team members.
• Identification of the locations of spill response equipment and materials for containment and
clean-up (spill kits and contents) as well as instruction on how to use them effectively. Locations
of product/material storage and spill kits should be readily identified on a figure or map and
posted in an appropriate location at the Project site.
The following represents the minimum scope for spill response/management procedures:
• Assess safety – ensure unnecessary people are kept clear of the area and that people with
proper training and equipment deal with the spill. Put on any required personal protective
equipment and consult Material Safety Data Sheets.
• Stop the source – if required, and when it is safe to do so, stop the spill at its source. This may
simply be righting an overturned container or sealing a hole.
• Contain and control the spill – the spill should be prevented from infiltrating into the ground or
entering a waterbody. If the spill occurs on water, booms should be immediately deployed to
prevent its spread.
• Clean up the spill – utilize appropriate absorbent pads or other materials based on the type of
substance spilled. The method of disposing of the waste is dependent on the amount and type of
deleterious substance that was spilled.
• Notify appropriate authorities – spills of a reportable quantity will be reported to the appropriate
agencies. Minor spills will be reported to the EM.
• Record the incident – make a note of what, how and where the incident happened as well as
what was done to clean it up. Depending on the spill, further assessment of the effect to land and
water and/or additional cleanup may be required.
Vancouver Fraser Port Authority Hemmera Maplewood CEMP - 19 - July 2018
When reporting a spill, the caller will provide the dispatcher with the following information, as accurately
as possible:
• Name and contact phone number of the person initiating the call;
• Name and telephone number of the person who caused the spill;
• Location and time of the spill;
• Type and quantity of the substance spilled;
• Cause and effect of the spill;
• Details of action taken or proposed;
• Description of the spill location and surrounding area;
• Names of agencies/responders on scene; and
• Names of other persons or agencies advised or to be advised concerning the spill.
